BREECH-LOA DING- GUN.

SPECIFICATION forming part of Letters Patent 116.369.964, dated September 13,1887.

Application filed January is. 1887. Serial No: 224,213. no model.) I'litantfld in Germany July 21, 1885, No. 34,266 in France September 4, 1885, No. 171,010; in Belgium June 4 1886 No. 13,354; in Italy June 30, 1886, XX, 20,056, XL, 48, and in Austria-Hungary September 30, 1886, No. 22,273 and No. 50,805.

To all whom it'may concern:

Be it known that I, CARL RiisTEI, a subect of the King of Prussia, and a resident of Buckau, near Magdeburg, Prussia, German Empire, have invented certain new and useful Improvements in Breech-Loading Fire- Arms, (for which I have obtained patents in the following countries, to wit: Germany, No. 34,266, dated July 21, 1885; France, No. 171,010, dated September 4, 1885; Belgium, Lo. 73,354, dated June 4, 1886; Italy, XX, 20,056, XL, 48, dated June 30, 1886; Austria- Hungary, N 0. 22,273 and No. 50,365, dated September 30,-1886,) of which the following is a specification. A

This invention relates tobreech-loadin g guns of that kind. or class wherein the breech-block 1s fitted to slide up and down in a chamber at the rear of the barrel and is arranged to be raised and lowered by means of a lever operated by hand.

The object of the said invention is to so construct guns of this class that the opening and closing of the breech, the firing, and the extractlng can be performed by one hand with out removing the same from the operatinglever. For this purpose I arrange the trigger in or upon the said lever and provide suitable means for connecting the said trigger with the sear.

In the accompahying drawings, Figure 1 is J a side elevation, and Fig. 2 a vertical longitudinal central section, of parts of a gun constructed-according to the present invention, showing the parts in the positions which they occupy immediately after the gun has been fired. Fig. 3 is a vertical longitudinal central Like letters indicate corresponding parts,

throughout the drawings.

ashaft, F, on which is also fixed a crank, f. l

The crank-pin j" is arranged to work in a curved slot, 0, in the breech-block C, so that when the lever E is moved in one or the other direction the said block will be raised or lowered.

G isthe hammer, which is pivoted at gand is acted upon by a spring, whereby it is driven at the proper time against the firingpin h. The hammer is drawn back or cocked by means of the operating-lever E in its upward and rearward movement through the instrumentality of the following parts: Rigid with the hammer formed on its shaft or pivot g isa shoulder, g, adjoining which is clearance g, for-permittingthe movement to and from saidshoulder of a second shoulder, it, formed on a part, 70, which I prefer to call the tumbler, similar clearance, It, being adjacent the shoulder k, for permitting the movement of the shoulder g. The tumbler k is shown in Fig. 7 as of. ring shape encircling the shaft 9, on which it is capable of independent movement to the extent permitted by the clearances g and it. One side of the tumbler is provided on its exterior with teeth k,which mesh with similar teethformed on a collar or segment, i, fixed rigidly to the shaft F.

Fig. 7 shows the positions which the parts occupy when the hammer is down and the operating-lever E in normal position.

To raise the hammer the lever E is moved from the position shown in Figs. 1, 5, and6 to that shown in Fig. 3. This moves the segment i in the direction of the arrow iflwhich in turn causes the tumbler It to be moved in the direction of the arrow k: The shoulders g and k being always in contact while the hammer is down, the latter impinging against the forward side of the ilormer, will cause the shaft 9 to move in unison with tumbler k, thereby ele-' vating the hammer until it arrives at cocked position, where it is held by the sear, in the manner hereinafter described. The operat- FOO ing lever may now be returned to its normal position, and in so doing the shoulders g k move through the clearances k and g, respectively. When the lever has arrived at its normal position and the hammeris left in cocked position, there will be aspace between the shoulders g" and k, through'which the shoulder moves during the descent of the hammer.- The said hammer is retained in its to cocked position by a scar, l, which is acted upon by a spring, 1', whereby it is caused to engage with a shoulder or projection, g, upon the shaft or pivot 91 as soon as this shoulder or projection has passed underthc said sear.

Pivotally connected to the scar Z is a'rod or pin, I, (hereinafter called the sear-pin,-f) at the-lower extremity of which is a lug, l pro-v jecting at right angles therefrom and entering a groove, 0, formed in the side of the operatzo ing-lever E, concentrically with its center of motion. This groove being concentric with the'shaft i, the movement of the lever E will of course have no effect upon the sear, while the groove e will operate to maintain the lower end of the sear-pin normally in fixed relation to the other parts. The trigger m is carried by andpivoted to the operating-lever E, and is coupled to a push-pin, m", which latter is provided. at its free extremity with a projection, m, workingin a groove or slot formed in the wall of the chamber D. (See Fig. 5.) This groove or slot has two branches, d and d, the latter of which is formed concentrically with the slot 0, butof greater radius, while the former intersects the plane of thesaid slot e. The result is that when the trigger is in its normal or forward position and theoperating-lever E in its normal or forward position,- the projection m on the free extremity of the push-pin m will occupy a position opposite both branches d and d of the groove. Now.

if, without pressing upon the trigger, the lever E be moved to shift the breech-block c,the projection on fromv the push-pin m will be movedinto thebranch dofthe-groo've, and while it remains in this branch it is manifest that it cannot act upon the sear-pin Z, because the groove d causes it to move in a plane outside of the plane of the projection Z. Now, if the operating-lever E be returned to its normal or forward position,the projection m again comes to the position shown in Fig. 5, opposite both branches d and d of the slot. If while the operating-lever remains in this position the trig- 5 5 ger is pressed, the push-pin m will be moved endwise in its bearing; and the branch d of the slot being directly in line therewith,it is mani fmt that the projection m will enter said branch and impinge against the lower extrem- 6a ity of the sear-pin Z, thereby'shifting it, and consequently the sear Z, freeing the hammer and permitting it to be impelled against the firing-pin by the spring 9.

For extracting theempty cartridge-shells from the barrel a lever, n, is pivoted at n, and is arranged to be operated in the downward movement of the breech block C by means of a pivoted piece, 0', carried by the said block. This piece 0' is acted upon by a spring, c, which normally holds the said piece in position to engage with the lever n, but which yields to permit thesaid piece to pass over the lever in the upward movement of the breechblock. Any other suitable means may, however, be used for effecting the extraction of the empty cartridges.

The operation of the gun is extremely simple. The gunner keeps the forefinger of his right hand uninterruptcdly 'upon the trigger. After firing the gun he turns the operatingleverE upward and thus opens the breech, extracts the empty cartridge from the barrel, and

' cocks the hammer; then, with-his left hand, he

pushesa fresh cartridge intothe barrel. He then turns the said lever downward and thus closes the breech, so that the gun is again ready for firing and his finger is in position to pull the trigger. a

I claim- .7
